Abstract:
Today, planners have the opportunity and obligation to address the challenge of global climate change.
The planning profession and the process of planning are uniquely suited to help communities rise to this
challenge of inculcating the climatic parameters in the process of development. We are trying to
understand these impacts of climatic change on the super system of Urban Planning for Development.
After grounding the major climatic impacts on development, we will look into the micro level planning,
reinstating our interdisciplinary studies in these sectors for development. Low Elevation coastal zone
(LECZ) houses almost 13% of World’s urban population and two thirds of world’s large cities with more
than 5 million population. These areas are not only environmentally delicate, but also house some of the
most important economic activities (McGranahan, Balk and Anderson 2007). According to IPCC
predictions, sea level can rise between 8-88cm between 2000-2100 AD (IPCC, 2001). A 1m rise in sea
level will have massive impact on land up to 10m above current MSL. With the increase in tendency
among people and development to move towards the coasts, sea level rise is a serious issue to be
considered in developmental decisions. For a coastal area that is prone to sea level rise, there should be
serious consideration in developing coastal areas that should take into account the relationship between
anthropogenic activities within these zones and environmental impacts of sea level rise.
Introduction:
The earth is getting warmer and it will continue to do so well into the future, creating a wide range of
impacts that include sea-level rise, droughts, and heat waves. The key question is how fast and how
severe the impacts will be and whether we can adopt policies for mitigating and adapting to these impacts.
Climatologists reporting for the United Nations Intergovernmental Panel on Climate Change (IPCC) see
human activities as almost certainly the major contributor to current global warming and express growing
fears that such warming will accelerate in the coming years with potentially devastating impacts.
In recent years, new scientific findings and media coverage have brought the issue of climate change to
the attention of planners, lawmakers and the public. Each of the last three decades has consecutively been
the warmest on record, validating the IPCC contention that climate system warming is “unequivocal.”
Scientists anticipate climate change impacts that include accelerated sea-level rise, drier conditions in the
South-western United States, higher amounts of precipitation in northern states, and more frequent heat
waves in every region of the U.S. These conditions make it imperative than planners and policymakers
work immediately to implement new policies to address climate change.
Scientists believe that the effects of human induced global warming cannot be eliminated because of the
volume of greenhouse gases (GHG) already emitted into the atmosphere., The IPCC 2007 Summary for
Policy Makers states that “(b)oth past and future anthropogenic carbon dioxide emissions will continue to
contribute to warming and sea-level rise for more than a millennium, due to the time scales required for
removal of this gas from the atmosphere.” Scientists also note that the rate and volume of future GHG
emissions can be reduced, lessening the extent of dangerous impacts on ecosystems, communities and
human health.
Consequently, responses to climate change can be put into one of two categories. Responses intended to
address the “cause” of human-induced climate change (e.g., production of CO2 and other greenhouse gas
emissions and deforestation) through reductions in vehicle-miles travelled, green building techniques, and
reforestation are classified as mitigation measures. Efforts to address the “symptoms" of climate change
(e.g., drought, intense precipitation, sea- level rise, and heat waves) through water resource management,
storm water control, coastal hardening, and providing shelters for at-risk populations can be considered
measures of adaptation.
The built environment is a primary contributor to climate change and GHG emissions. Roughly 50
percent of human-caused GHG emissions result from heating and cooling buildings and from transporting
people and goods. Planners have significant opportunities to reduce emissions from these sources through
promotion of multimodal transportation alternatives, compact development patterns, energy-efficient
building siting and design, urban forestry, local foods, conservation of natural areas and resources,
sustainable capital investments and economic development, low impact development practices, and many
other initiatives and activities.
Additionally, both the built and natural environments are at risk from climate change impacts that will
occur regardless of the extent to which GHG emissions are mitigated. Flooding, drought, stronger storms,
sea-level rise, and higher temperatures will challenge the resilience of built and natural systems. Planners
have the opportunity to help their communities adapt to these impacts by identifying vulnerable
populations and ecosystems and developing plans to enhance their resilience.

Types and Levels in Climate Changes
Sea Level Rise:
The projected increase in global warming by the middle of the next century ranges from 1.5 to 4.5 deg C.
(Barth and Titus, 1984). Sea level changes can be of two types: (1) changes in the mean sea level /
Eustatic and (2) changes in the extreme sea level/local. The former is a global phenomenon while the
latter is a regional phenomenon. (Unnikrishnan, Kumar, Fernandes, Sharon, Michael, Patwardhan, 2006),
these impacts will depend not only on local geomorphologic factors but also on the climatic fluctuations
and the coastal practices of the region. While the eustatic rise in sea level is uniform the rise in relative
sea level and consequent impacts are essentially regional. The choice of response will also necessarily
have to be location and resource specific, given the variations in these effects in the socio economic
characteristics of the region and in the response capabilities of nations.
A rise in sea level represents a potential threat to existing coastal economic, social and environmental
systems. The effects of sea level rise can be classified into four broad categories: Physical,
ecological/environmental, socio economic and legal & institutional. Increasing trade and market driven
movements, often supported by government incentives are still attracting people to the coast. This has
also led to an increase in net in-migration to these zones world over. The main driver of city expansion (or
stagnation or contraction) is where new or expanding profit seeking enterprises choose to concentrate (or
avoid). This is also largely true for how each urban centre develops - as the localities or districts within
and around the urban centres with the most rapidly growing population is associated with where new or
expanding economic activities concentrate (torres, Alves, Aparecida de Oliviera, 2007). Attempts by
government to change the spatial distribution of their urban population or of the economic activities that
underpin urban development can impose high economic costs - as this undermines the economic success
of enterprises. Therefore, it is important to look at the vulnerability of both natural resources and the
human activities that are dependent on it. Broadly SLR will affect land, people and their activities and
natural environment and ecosystem. Potential land lost to SLR is due to inundation and erosion. This is
mainly because there are large areas within 1 m elevation of present high water partly reflecting the
extensive areas of natural and claimed intertidal habitat
around the world‟s shores. Above 1m elevation, land area is
an almost linear as a function of elevation, although the
threatened area does diminish slowly with elevation. Over
5x10^6 sq. km lies within 10m of the mean high water levels
and 8x 10^6 Sq. km lies within 20m of mean high water
levels across the globe (Brooks,Nicholls,Hall,2006).
Erosion is the physical removal of materials from coastal
areas which is likely to increase as a result of SLR .The
simple „rule of thumb‟ from the Bruun Rule suggests that
erosion is roughly 100 times the rise in Sea level
(Nicholls,1998). Inundation is likely to be more important
process than erosion (Walkden and Hall, 2005). Population
and activities are under risk from inundation and flood. A
1995 estimate puts almost 60 million people to live within 1m
and 275 million within 5m from mean sea level. These figures
are projected to increase to some 130 and 410 million
respectively by the end of the 21st century (Nicholls, 2004). Therefore, assuming a constant population or
Hazira Topography. (Source: CEPT, 2004)
spatially uniform population growth, roughly 10% of the World‟s population could be displaced by a 10m
rise in Sea level and 15% of the World‟s population could be displaced by a 20m rise in Sea level. When
trends are extrapolated to the decade of 2080s and assuming to be fixed thereafter, 0.9 to 2.6 billion
people might have to be relocated away from land threatened by inundation.
The Case: Hazira, Surat.
Hazira is one of India‟s and Gujarat‟s most significant industrial concentrations, located along the western
seacoast just off the city of Surat. The Hazira area has a large concentration of nearly 20 medium and large
industries with a combined capital investment of over Rs. 350,000 million (2003). This is expected to rise
to over Rs. 500,000 million (2025) of investment in the near future and represents nearly a third of the
industrial investment in Gujarat and a tenth of its economic output. The Hazira area has many strategic
advantages, including easy access to the sea, a major trunk railway network; ensured energy supplies;
connectivity to a major city and trading centre with well-established institutions of commerce, industry
and education.
During the last two decades (1981 to 2001) Hazira has witnessed phenomenal growth in terms of
industrial activities, resulting in mammoth investment in very strategic areas. With better linkage to the
Golden corridor and the available sea front, it has attracted few of the major industries such as ONGC,
KRIBHCO, L&T, ESSAR etc. to set up their industries in this area. Hazira is a classic example of port
and infrastructure lead development, a stand taken by Gujarat government to promote industrial growth
in the state.
The physical boundary of Hazira is defined b y waterfront on three sides. On the southern side,
flows the river Tapi, on the western part is the Arabian Sea and on the northern part is the Tena
creek. On the eastern part it is linked with Surat city. The river Tapi flows throughout the Surat
district and merges the Arabian Sea on the southern part of Hazira region. At the southern part it
bifurcates into two branches near the village Kavas - Limla. The right branch flows towards the
agricultural lands of the Mora and Suvali villages making an island known as Gajrabet & Aliyabet.
This branch of river is navigable and useful for small boats, powerboats, barges and ships. However,
navigability of this section has been reduced.
Hazira has a total coastline of 30 kms starting from southern tip
(Hazira village) upto the northern part of Tena creek. The
Arabian sea forms two sea water insurges in the villages of
Rajagiri and Suvali along its coast. This causes flooding during
high tide and monsoons. The villages Suvali, Mora, Vansva,
Damka, are affected due to this (CEPT, 2004). Area selected for
study consists of notified area of Hazira measuring 168 Sqkm.
The whole area has been subdivided into unit squares of approximately 0.5 Sqkm each. But the total
land available for development after reducing water bodies and wetlands is 106 Sqkm.
The Government of Gujarat has identified Hazira as a thrust area for major industrial development. The
location advantages of this area have attracted several large and medium scale private, public and joint
sector industries. Most of these units use natural gas as their basic resource. Approximately 20 large
and medium sized industries are located in Hazira. It houses industries like KRIBHCO, L&T, ONGC,
IOC, NTPC, Reliance, ESSAR etc came into existence.

The bulk of the existing industrial plants are located along the river or seaside to enable access to the
water for transportation. However, this has placed them directly in the plain, inter-tidal zone or along
the CRZ – exposing them to considerable risk to water related hazards. Two major driving forces for
industrial development in this area are availability of cheap land and natural gas via ONGC‟s offshore
pipeline from Bombay High. The ready availability of gas is expected to enable the significant expansion
of existing facilities and development of new medium and large-scale industries in the area in future.
In order to service these industries, two ports at Hazira and adjoining port of Magdalla, significant
investments in terms of port and berthing facilities and emphasis on development of better infrastructure
facilities has been addressed in the master plan prepared for 2025 (CEPT,2004).
The estimated current capital investment in the region is over Rs 365,000 million. Close to Rs 190,000
million of proposed investment is awaiting environmental clearance. In addition to this, a significant
volume of investment is expected to flow into the Hazira area with the expansion of current industrial
unit capacity and in response to the new multiple purposes all weather Shell port that is being developed.
The projected total investment is expected to exceed Rs 550,000 million.
Using the Incremental Capital Output Ratio (ICORs) for the Gujarat economy, the estimated gross value
of sales of the current investment in the Hazira is close to Rs 650,000 million (at current prices). This is
expected to rise over Rs 1,000,000 million once new units in the pipeline are established. Using a
conservative estimate of 20 percent of gross value added of gross sales, the current Gross Value
Added (GVA) could be estimated at Rs 130,000 million. Future the GVA could rise to close to Rs.
200,000 million.
This would place Hazira at close to 27 percent of the industrial investment in Gujarat and about11
percent of the GVA of the state. This massive industrial concentration is, therefore, critical not only to
Gujarat but also to the Indian economy.
The bulk of the Hazira peninsula consists of inter-tidal region and coastal plains with low ridges on
which traditional settlements are located. Before its industrial development and intervention of laying of
roads and other structures, there would have been a largely unimpeded flow of tidal waters in and out of
Hazira as can be observed from topography map from the Survey of India (CEPT, 2004).
The physical consequences of sea level rise can be broadly classified into three categories: shoreline
retreat, temporary flooding and salt intrusion. The most obvious consequence of a rise in sea level would
be permanent flooding (inundation) of low-lying areas. Many coastal areas with sufficient elevation to
avoid inundation would be threatened by a different cause of shoreline retreat: erosion. It also alters the
relationship of shore profile to water level. With this context it is important to look at the existing hazard
risks of Hazira.
The above table shows that a 1m rise in sea level would have a dangerous impact on the existing
industries and infrastructure as well as the proposed ones. But unlike other hazards, Sea level rise is
not a one-time process it is a gradual phenomenon. Therefore Time becomes an important factor for
determining the impact SLR will have on the economy of a place. With the above knowledge on
topography, hazard vulnerability and the resources of the Hazira region, it is necessary to work out
the critical year and the subsequent economic loss. For this, two levels of analysis has been conducted
one to arrive at the critical year and the other at the economic loss.
Adaptation and Mitigation
In order to answer these questions, it is necessary to first look in detail what is adaptation and mitigation
and how it will affect the current industrial, land use regulations and coastal management policies.
Analytical Framework:
There are numerous methods that are
available to prevent, mitigate and
respond to erosion, flooding and salt
water intrusion from sea level rise.
Communities and individuals must
decide whether to attempt to protect
themselves from the consequences of
sea level rise or adapt to them.
Generally, prevention will be
economically justifiable only at
valuable locations such as population
centres, defence installations, historical sites and areas of environmental importance.
Prevention of erosion requires keeping waves from attacking the shore. This is generally achieved by
intercepting the waves offshore or by armouring beach itself. Offshore breakwaters limit the size of
incoming waves. Revetments armour the beach itself and can be useful for moderate size waves.
Several means of preventing inundation and storm surge also serve to limit erosion. Seawalls, levees and
bulkheads are vertical wall structures made of materials of various strengths, depending on the size of the
waves. With a rising sea, however these structures may require protection themselves.
Adjustment to the physical consequences of a sea level rise may sometimes be more appropriate
than prevention. Policies must address this issue to prevent subsequent losses to effects due to sea level
rise. In the case of Hazira, there are two sets of industries: 1) Already existing ones 2) proposed
industries. Issue of adaptation of these industries must be dealt differently at policy level. Therefore, it
is necessary to review the current Industrial policy of Gujarat. Also coastal management must put in
place regulations for such heavy developments along coasts. Development control regulations of
urban bodies, in the case of Hazira, regulations made by Surat urban development Authority were
reviewed.
Adaptation and mitigation measures at various levels:
According to coastal regulations Hazira falls in the CRZ-III zone i.e. Areas that are relatively
undisturbed and those, which do not belong to either Category-I or II. These will include coastal zone
in the rural areas (developed and undeveloped) and also areas within Municipal limits or in other legally
designated urban areas that are not substantially built up. Major observations after studying the CRZ-III
are:
• The existing industries in Hazira have encroached the 500m mark from the high tide line.
• Also existing construction and filling up of low-lying areas for industries has altered the original
tidelines.
• The proposed industrial development (Hazira Area Master plan) also do not completely follow CRZ
III regulation.
This calls for reworking the CRZ regulations and HTL. With the gradual increase in SLR, which is bound
to happen in another 100-years‟ time, it is important to decide on the shifting HTL and how
development should address this issue. It requires a detailed analysis of the current land use and
development control regulations and areas of intervention at the local level.
The most fundamental question suggested by the study on effects of sea level rise is whether to retreat
or hold back the sea. Scientists have predicted the gradual conversion of agricultural and higher
productive land into wetlands. Few suggestions in literature includes government to purchase land or
prohibit development, but the usefulness of this approach is limited due to high expense in purchase of
land and the assumptions in sea level rise predictions. To channel new economic development to high
ground whenever possible would be the most highly recommended suggestion.
Hazira area is governed by Hazira notified area authority and is proposed to have an independent
governing authority called Hazira Area Development Authority. Looking at most of the cities and their
governance structure, the land use zoning is done by city urban development authority. A part
of the 168 Sq. Km of Hazira areas lies in Surat Urban development authority (SUDA) and the
growth of this area is governed by SUDAGDCR – General Development control regulations.
Surat urban development Authority‟s Development control regulation has been reviewed for land use
zoning restrictions in hazard prone areas and how it addresses the issue of industrial location. Major
findings include:
• The frequency/return period of floods and storm surge/cyclone in Hazira is very high for 100yr return
period.
• Current GDCRs provides options of physical intervention in flood-affected areas, than future safe
zoning of such areas.
• Hazira though falls under the category of land mentioned under para 6, the developments

Mitigation Higher level (national / International) policy options
Local level mitigation measures (permanent and temporary structures)
Adaptation Existing Industries

Industrial Incentives to combat natural disasters
Proposed Industries
Land use regulation
Coastal zone management
Industries location policy
are not according to that.
• This clause may be applicable in Hazira, however steps taken to implement this is yet to be looked
into.
It is clear from this analysis that development control regulations must not only look at Hazira as a hub
of economic activities but also from vulnerability of these economic activities to an environmental threat
that is gradual. This questions the relevance of adaptation options for the existing industries, which has
further life span of more than 25 years, and for the proposed industries to be located within the Hazira
Notified Area. This calls for a separate development model for Hazira notified area and such similar
precincts dotting Indian coastline. This leaves us with major questions: What could be the adaptation
strategy for areas similar to Hazira that have high economic productivity and high threat from natural
disasters? What are the policy level interventions to be made and who all will be the major players?
Currently these are the grey areas and need immediate attention not only at the micro level but also
at the macro decision-making level.
Adaptation Strategies:
Adaptation strategies could be at two levels:
• Micro adaptation strategies
• Meso level adaptation strategies
Factors that affect investment in Hazira and adaptation strategies at various levels
Micro adaptation strategies
In areas like Hazira, micro level adaptation strategies can be more effective than larger area or meso level
strategies.
This can be further sub divided into:
MESO LEVEL: Region specific and Activity specific and,
MICRO LEVEL: Site specific and Industry specific.
It is interesting to note at the global front what are the strategies adopted for adaptation to sea level rise at
micro levels:
• Rising dykes all along the vulnerable areas
• Abandoning of low lying areas
• Shifting all activities to highlands
• Building sea wall and rising structures on stilts
• Land use planning policy to reflect a “hold off wait and see” attitude; moratorium on
development.
• Create a margin of liberty for the sea (review, alter and condemn the building zone)
• Cost benefit analysis of protection options, study and model possible features.
• Create a condition for possible retreat (accompany the population on economic, social and
psychological levels)
• Redistribute local economy
• A combination of accommodation and retreat is more likely the adaptation strategy.
In all the above cases the adaptation strategy could be through physical measures or policy measures.
But this may have impact on the site as well as its surroundings, unique to each case.
With the above said strategies, if we try to analyze the case of Hazira, there are three levels of adaptation
that one needs to address:
• Disaster preparedness and awareness among the investors and the region as a whole
• Time of highest impact having an effect on the type of industries and industry lifecycle.
• Land use zoning and how it affects the existing industries and proposed ones.
All of these will directly impact the investments in Hazira. Thus this calls for coordination from various
government agencies to develop a development model for regions of high economic value and worst
affected by natural disasters. Various agencies and statutory bodies responsible and their functions have
been identified, while, it is beyond the scope of this study to designate the levels of intervention.
Conclusion
A 1m sea level rise is bound to happen anytime between 2000 to 2100 AD. With the rise many of the
low elevation coastal zones are going to be adversely affected in terms of economic as well as social
loss. India with its long coastline and large investments along the coast will be one among the worst
affected. The effect can be felt especially in large coastal investment hubs such as Mumbai, Cochin, Surat,
etc. on the western coastal strip of India. Gujarat being the most industrialized state with the largest
coastline will be one of the worst hit in terms of economic development.
The most important factor here is the time at which the region will be worst hit. The main aim of the
study was to develop an analytical framework for determining the decision making to locate an
economic activity in such low elevation coastal zones threatened by sea level rise. A case of Hazira was
used to demonstrate the effects and the probable time of maximum threat with various sea level rise
scenarios. In the context of Hazira one needs to consider both mitigation and adaptation options, even
though the country has very limited scope for mitigation. This is because mitigation options involve
global efforts to execute and adaptation options are more local in nature. So, effective adaptation
policies should be developed and implemented to minimize sea level rise impacts on Hazira.
Hazira was used to demonstrate the ill effects of planning economic centres with little emphasis to
gradual environmental threat like sea level rise. There are many more such vulnerable sites attracting
large scale investments all along the Western as well as Eastern coast of Peninsular India. Most of the
current development activities have been planned without taking into consideration a potential threat
from natural hazard such as sea level rise. Therefore, with a potential threat like sea level rise and with
its numerous manifestations and high uncertainties, will have a massive impact on our country‟s
otherwise potential LECZs. It is high time we channelize the current growth taking into consideration the
future threat instead of troubleshooting. This calls for better understanding of current and future
scenarios with coordination from various stakeholders at macro, meso and micro levels including
state and central government to take precautions and policy level interventions at both physical as well as
policy levels.
Planners have been involved in activities that have had positive climate change impacts for a long time.
Efforts to combat sprawl through promotion of a more compact land use pattern, for instance, result in
fewer vehicle-miles travelled, reducing the amount of greenhouse gases going into the atmosphere.
Virtually every community has a natural disaster response plan that can be modified to help citizens adapt
to climate change effects. However, these different efforts have seldom been placed under the umbrella of
climate change. As a result, there are few comprehensive efforts to address climate change at the local
government level.
This is starting to change.
For the last decade, planners have rightly focused on smart growth and sustainability but have not always
seen them as directly connected to climate change. The American Planning Association ratified policy
guides on both topics, in addition to this one for climate change. Innovation in these areas has been
important; however, the growing climate crisis and the emerging policies to address it make it essential
for planners to respond to climate change issues now. Policy action on climate change is happening across
the nation. More than 500 cities have pledged to significantly lower their emissions and, the majority of
states now have special commissions or adopted action plans on climate change. Nearly half have already
set overall GHG emission or vehicle-based GHG emission targets. Many have developed adaptation
plans. The American Planning Association maintains a resource database on energy and climate change
issues on its webpage that chronicles the work many communities are doing in this area. Planners will be
called upon to implement many aspects of these new programs and craft plans that meet new emission
targets and address adaptation concerns.
Planning can play an important role in influencing societal actions that can slow the pace of climate
change, mitigate the effects that do occur and allow adaptation to the ultimate impacts of global warming.
The planner‟s role will be extremely important because it will deal with such basic issues as community
design, transportation networks and use and increasing development density. Elected leaders and citizens
will rely on plans, direct
investment, design, and development strategies that are efficient and sustainable and which comport with
other community priorities. Planners will also have to address the potential
costs imposed on households by climate change and the policies adopted to address it. The climate
challenge will require the comprehensive, long-term perspective that planning is uniquely qualified to
provide.
Four ideas form a framework for this guide. First, the policy responses to climate change need to be based
on the best possible science. Because climate change is bringing about
previously unrecorded conditions, projections based on new scientific modelling are the best
way to anticipate and respond. Planners must have access to vital data, information and resources to help
them interpret these unprecedented changes
Second, the specific impacts of climate change are highly regional and even local in nature. Therefore,
climate change policies cannot be based on a one-size-fits-all approach. Planners must be aware of what
the future holds for their particular geographic region and formulate their strategies accordingly. While
plans and policies must reflect the individual needs of local areas, any successful mitigation effort will
require a national, and indeed international, framework for addressing GHG emission.
Third, adapting to climate change is just as important as mitigating it. Planners can have a significant
effect on climate change mitigation through a variety of actions, including encouraging higher density
development, reducing vehicle-miles-travelled (VMT), using green building techniques, and supporting
alternative energy sources. However, due to the extent of potential impacts projected under even the most
aggressive mitigation scenarios, planners will also need to address the effects of climate change including
rising sea levels, greater drought conditions and flood control in planning for adaptation.
Finally, planners need to communicate about climate change in new and different ways. Policies that we
develop now will have a long-range timeframe. Given that it is often hard to keep people engaged over
even the short-term, planners will need new communication tools to explain climate change issues and
maintain the focus on long-term adaptation and mitigation responses. Citizen participation and
engagement is vital to the success of climate change efforts.
Planning is vital because of its comprehensive approach to the built environment, but traditional
approaches are not enough to mitigate and adapt to climate change.. A dramatic new response to climate
change is required. Business as usual or small, marginal reforms will not suffice. The nation and our
communities must commit to incorporating climate change considerations in a thorough, comprehensive
new approach to physical, social and economic planning. Planners must promote this major shift in the
public policies that drive development decisions, growth and infrastructure investment.

Smart Growth, Sustainability and Climate Change Responses
Many communities have invested considerable effort in producing smart growth and sustainability plans
to encourage a more effective and efficient use of resources, to promote sound fiscal policy, and to
achieve infrastructure, economic development, social equity, and environmental objectives. Virtually all
of these initiatives have positive outcomes for climate change responses. For example, a more compact,
interconnected development pattern reduces vehicle emissions (a climate change goal) while promoting
efficient use of infrastructure, public health and environmental stewardship (all smart
growth/sustainability goals).
Consequently, it is important for planners to recognize that many climate change responses are ones that
can be undertaken for a variety of other important reasons. There is a demonstrated synergy between
reducing GHG emissions and fiscal and environmental sustainability, or between improving community
resilience to climate change impacts and smart growth infrastructure decisions. Decision makers may be
more inclined to reduce commuter costs than to reduce GHG emissions, for example, allowing planners to
make progress in climate change responses in an indirect fashion.
By promoting the synergy between smart growth, sustainability and climate change mitigation and
adaptation, planners can affect positive outcomes through a so-called “no regrets” approach, whereby
actions taken to adapt to or mitigate climate change are ones that should be taken anyway for other
reasons related to smart growth and sustainability.
Social Equity and Climate Change
Planners are required to address social equity in their work as part of APA‟s AICP Code of Ethics and
Professional Conduct. As Hurricane Katrina and heat wave mortality figures teach us, lower income and
elderly populations are more at risk and will bear the brunt of many climate change impacts. Additionally,
indigenous populations, particularly American Indians subsisting in traditional ways in the Pacific
Northwest and Alaska, will also face significant difficulties disproportionate to other populations as a
result of climate change.
As a consequence, planners need to ensure that the responses they develop to address the impacts of
climate change take into account the varied needs of all sectors of the community in order to equitably
meet the significant challenges facing us.
